OBJECTIVE: We explore the role of DNA methylation in Alzheimer's disease (AD). To elucidate where DNA methylation falls along the causal pathway linking risk factors to disease, we examine causal models to assess its role in the pathology of...

Brain microRNAs associated with late-life depressive symptoms are also associated with cognitive trajectory and dementia.

NPJ Genom Med. 2020 Feb 06;5:6. doi: 10.1038/s41525-019-0113-8. eCollection 2020.

Late-life depression is associated with an increased risk for dementia but we have limited knowledge of the molecular mechanisms underlying this association. Here we investigated whether brain microRNAs, important posttranscriptional regulators of gene expression, contribute to this association. Late-life...

Brain Sci. 2017 May 23;7(6). doi: 10.3390/brainsci7060056.

With the aging of the U.S. population, the number of cognitively disabled persons is expected to substantially increase in coming decades, underscoring the urgent need for effective interventions. Here, we review the current evidence linking psychosocial factors to late-life...
